Providing and fixing in position wall panelling at all heights with integral densified calcium silicatepanels/tiles of size 595 x 595mm, having NRC (Noise Reduction coefficient) of 0.50 (minimum) as per IS8225:1987, Light reflectance of 85% (minimum). Non combustible as per BS:476 (part-4), fireperformance as per BS:476 (part 6 &7), humidity resistance of 100%, thermal conductivity <0.043 W/m Kas per ASTM 518:1991, comprising of a frame made from especially fabricated galvanised mild steelsheet 0.50 mm thick pressed section (galvanizing @120 grams per sqm including both sides) i.e.verticalstuds of size 48 x 34 x 36 mm are placed at 600mm center to center in a floor and ceiling channelsection of size 50 x 32m fixed to the floor and soffit at 600mm centers using 12mm dia,50mm long wedgetype expanded zinc alloy dash fastner with 10mm bolt. This same channel is then to be fixed inhoriziontal direction at 600mm center to center so as to form a grid of 600mm x 600mm. Glasswool of50mm thickness is then to be inserted in the slots and finally calcium silicate non combustiblepanels/tiles are to be screw fixed with self tapping pan head nickel coated mild steel screws of size 13 x3.2mm on to this grid leaving an even groove of 1 mm between the panels. The joints between the panelsare to be duly jointed and finished using recommended jointing calcium silicate based compound andfiber joint tape roll 50mm wide (90 metre )roll and two coats of primer suitable for panelling as permanufacturer's specification as per direction of Engineer-in-Charge all complete.
With 15 mm thick fully perforated square/butt edge light weight calcium silicate panels/ tiles
